IMPROVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent N0. 143,592, datedOctober 14, 1873; application filed August 2, 1873.

To all whom it may concern:

Be it known that I, LoUIs SCHULZE, of Ghicago, in the county of Cook and State of Illinois, have invented an Improvement in Axle- Boxes for Railway-Gars, of which the following-is a specication:

vThis invention has for its object to provid an axle-box with a drawer for containing oil for lubricating the journal, and a device for distributing oil to the journal while it is Iin m0- tion, in lieu of the cotton waste or other fibrous material heretofore used ,for that purpose, and which is not only expensive, but partially neutralizes the lubricating properties of the oil, and frequently induces the heating of the journal. The invention consistsiu the construction andarrangement, with relation to the box,

of a penduliun-lever, as more fully hereinafter set forth.

Figure lis a longitudinal vertical section on xw in Fig 2, which is a cross-section of the box on y y in Fig. l. Fig. 3 is a perspective view of the box closed. Fig. 4 is a perspective view, showing the oil-drawer partially drawn out.

In the drawing, A represents an axle-box, open at the outer end. B is the journal of the axle, and C its brass or bearing, on which,

the top of the box rests. D is a drawer, preferably of cast metal, adapted to slide into the box and close its outer end, where it is secured by a pendulum-lever, 1E, pivoted to a lug at the top of thebox, which swings downV in front of the drawer. The drawer has a 'trough-like cover or sunken top, D', to adapt it to slide under Ithe axle, while it 'will also keep the oil from splashing out.` It is also transversely slotted through the middle of the cover to admit a cork wheel, F, mounted on a shaft, a, which projects from each side into a vertical guide chamber or groove, b, pendent from the cover at each side of the slot. c is a channel or oil-duct cast in the 'front of the drawer, leading into it below the cover, through which the former can be filled without withdrawing it from the box. d is a rubber washer inserted in a recess or cavity formed in the projection at the lower end of the vpendulumlever, and is of such shape as to protrude from an opening in its inner face, so that when the pendulum is dropped the projecting portion of this washer will enter the mouth ofthe oil-duct c and close it against the entrance of dust,

caused by the lint from it getting' into the bearing.

If the drawer be properly fitted no dust will get into the box, muclliltime is saved in oiling up, there are no boltsf'lor box-covers to be lost, and the condition of the drawer can be seen in a moment by partially drawing it out of the box.

What I claim as my invention, and desire to secure by -Letters Patent, is-

The pendulum-lever E, pivoted to the box A, and provided with the inwardly-proj ecting washer d, with relation to the oil-duct c of the drawer D, as and for the purpose set forth.
